  According to the present feature configuration, for example, the control unit performs guidance control, so that, for example, the area near the place where the platform is installed is a comfortable environment for humans to exist, and the other area is more than the area near the place where the platform is installed. It is possible to guide a person to the vicinity of the place where the platform is set by changing the environmental state between the plurality of areas so as to make the environment less comfortable. Thereby, people in the control target space can be gathered in the vicinity of the place where the platform is installed, and an environment in which lessons, meetings, lectures, etc. can be efficiently progressed can be created. Moreover, in areas other than the vicinity of the platform installation location, the comfort may be lower than the proximity of the platform installation location. For example, the operation of the facility is stopped or the operation capability of the facility is reduced. By doing so, the power consumption of the facility can be reduced, and energy can be saved.

  The second characteristic configuration of the present invention is provided with a counting unit that counts the number of people in the control target space, and the control unit is configured to provide a plurality of areas according to the number of people counted by the counting unit as the guidance control. The guidance area including the vicinity area of the platform installation location is selected from, the environmental state is different between the selected guidance area and other areas, and the person in the control target space is guided to the guidance area. It is in.

  According to this feature configuration, the control unit selects the guidance area including the vicinity area of the platform installation location according to the number of people in the control target space, so the neighborhood area of the platform installation location is always selected as the guidance area. The width of the guidance area can be adjusted according to the number of people in the control target space. As a result, even if the number of people in the controlled space changes, it is possible to guide the people in the controlled space to the guidance area according to the change and appropriately create an environment where classes, meetings, lectures, etc. can proceed efficiently. .

  Returning to FIG. 1, the count unit 6 is configured to count the number of people in the classroom 1 from the image data when the image data obtained by the camera 7 (web camera) provided on the ceiling is received. Has been. A plurality of cameras 7 are arranged so that the entire classroom 1 is an imaging range, and image data is output to the count unit 6 in real time.

  The control part 5 and the count part 6 are comprised from the terminal device (personal computer) which has various information processing functions, for example. Although FIG. 1 shows an example in which the control unit 5 and the count unit 6 are configured by separate terminal devices, the control unit 5 and the count unit 6 can also be configured by one terminal device. The configuration of the counting unit 6 can be changed as appropriate.

  The control unit 5 controls the lighting device 2 and the air conditioner 3 in a form in which the environmental state is different among the plurality of regions R1 to R5, and guides people in the classroom 1 to the vicinity region of the platform setting location of the platform 10. It is comprised so that guidance control may be performed. The control unit 5 selects, as guidance control, a guidance area including a region near the place where the platform 10 is placed from a plurality of areas according to the number of people counted by the counting unit 6, and the selected guidance area and the others The people in the classroom 1 are guided to the guidance area with different environmental conditions.

Hereinafter, the guidance control of the lighting device 2 and the guidance control of the air conditioner 3 will be described separately.
In the guidance control of the lighting device 2, when the number of people counted by the counting unit 6 is less than the first set number (for example, 100 people), the control unit 5 selects the adjacent region R1 as the guidance area. When the number counted by the counting unit 6 is equal to or greater than the first set number and less than the second set number (for example, 200), the control unit 5 selects the adjacent area R1 and the rear area R2 as the guidance area. If the number counted by the counting unit 6 is equal to or greater than the second set number, the control unit 5 selects the adjacent region R1, the rear region R2, and the side region R3 as the guidance area. And the control part 5 performs the driving | operation of the illuminating device 2 in a guidance area so that the selected guidance area may be lighted, and stops the driving | operation of the illuminating device 2 outside a guidance area so that areas other than a guidance area may be lighted out. .

  In the guidance control of the air conditioner 3, when the number of people counted by the count unit 6 is less than the third set number of people (for example, 150 people), the control unit 5 selects the front area R4 as the guidance area. When the number of people counted by the counting unit 6 is equal to or greater than a third set number of people (for example, 150 people), the control unit 5 selects the front area R4 and the rear area R5 as the guidance area. Then, the control unit 5 operates the air conditioner 3 in the guidance area so as to perform air conditioning in the selected guidance area, and operates the air conditioner 3 outside the guidance area so as to stop air conditioning in areas other than the guidance area. To stop.

  By performing guidance control of the lighting device 2 and the air conditioner 3, only the guidance area including the vicinity of the place where the platform 10 is installed is lit and air-conditioned, and a comfortable environment is created even in the presence of a person in the guidance area. A person in 1 can be guided to the guidance area. Therefore, while reducing the power consumption of the lighting device 2 and the air conditioner 3 and saving energy, the class can be conducted in a state where the students are gathered in the area near the place where the platform 10 is installed, and the class can be efficiently advanced. be able to.

  As described above, since the output of image data from the camera 7 to the counting unit 6 is performed in real time, the number of persons in the classroom 1 is counted by the counting unit 6 in real time or every time the set period elapses in guidance control. can do. Therefore, the control unit 5 repeatedly selects the guidance area in real time or every time the set cycle elapses, and switches the illumination device 2 and the air conditioner 3 between operation and operation stop according to the selection of the guidance area. Can do. Thereby, for example, even when the number of people in the classroom 1 increases or decreases during the lesson, the guidance area can be changed according to the increase or decrease of the number of people to appropriately save energy and improve the efficiency of the lesson.

  Here, for example, an artificially operated switch is provided for the controller 5 to select whether or not to perform the above-described guidance control, and the state in which the guidance control is performed and the equipments 2, 3, 4 without performing the guidance control. Can be switched to a state in which the driving state can be adjusted by human operation.

  Since the classroom 1 is provided with the ventilation device 4 in addition to the lighting device 2 and the air conditioning device 3, the control unit 5 controls the operation state of the ventilation device 4 according to the number of people counted by the counting unit 6. doing. The ventilation device 4 is configured to be capable of adjusting the ventilation amount in the classroom 1 in a plurality of stages (for example, three stages of minimum ventilation, intermediate ventilation, and maximum ventilation). When the number of people counted by the counting unit 6 is less than the first set number of people (for example, 100 people), the control unit 5 adjusts the ventilation amount of the ventilation device 4 to the minimum ventilation amount and operates the ventilation device 4. When the number of people counted by the counting unit 6 is equal to or greater than the first set number of people and less than the second set number of people (for example, 200 people), the control unit 5 adjusts the ventilation volume of the ventilator 4 to the intermediate ventilation volume and performs ventilation. The device 4 is operated. When the number of people counted by the counting unit 6 is equal to or greater than the second set number of people, the control unit 5 adjusts the ventilation amount of the ventilation device 4 to the maximum ventilation amount and operates the ventilation device 4.

  The control unit 5 performs preliminary control prior to the above-described guidance control. This preliminary control is control for ensuring minimum lighting, air conditioning, and ventilation as an environment in the classroom 1. For example, the control unit 5 operates the lighting device 2 and the air conditioner 3 only in the preliminary operation region, stops the operation of the lighting device 2 and the air conditioner 3 in the other region, and ventilates the ventilation device 4. The ventilation device 4 is operated by adjusting the amount to the minimum ventilation amount. At this time, the preliminary operation region for the lighting device is defined as an adjacent region R1, and the preliminary operation region for the air conditioner is defined as a front region R4.

  Thus, the control part 5 can aim at energy saving, ensuring minimum illumination, air-conditioning, and ventilation amount as the environment in the classroom 1 by performing preliminary control before the start of a lesson. And the control part 5 can aim at energy saving and efficiency improvement of a lesson by shifting to a guidance control from a preliminary | backup control with the start of a lesson. The transition from the preliminary control to the guidance control is not limited to the start time of the lesson, but may be before the set time, and can be changed as appropriate.

  Moreover, the control part 5 can transfer to guidance control from preliminary | backup control with the completion | finish of a lesson. The timing of this transition is not limited to the end of the lesson, and can be shifted as the set time elapses from the end of the lesson, for example. As a result, the control unit 5 performs guidance control during the class and performs preliminary control between classes or during lunch breaks, and performs one-day control such as preliminary control → guidance control → preliminary control → guidance control. As a form, preliminary control and guidance control can be repeatedly performed.

[Another embodiment]
(1) In the above embodiment, the classroom 1 in which the platform 10 is installed is used as a control target space. As long as it is a space, various spaces can be used as control target spaces. In addition, the position of the platform 10 or the platform such as the podium can be appropriately changed in which position in the control target space.

(2) In the above-described embodiment, one air conditioner 3 is provided for each of the front side region R4 and the rear side region R5 divided as regions for the air conditioner. As in the area for the lighting device, the area is divided into three areas of the adjacent area R1, the rear area R2, and the side area R3, and guidance control is performed by the two air conditioners 3 at the front side position and the rear side position. You can also

  For example, when the adjacent region R1 is selected as the guidance area as the guidance control of the air conditioner 3, the control unit 5 operates the air conditioner 3 at the front side location and sets the air conditioning capability to the first setting capability (for example, 70% capacity). And when adjacent area | region R1 and back area | region R2 are selected as a guidance area, in addition to the driving | operation of the air conditioner 3 of the front side location by the 1st setting capability, the control part 5 is the air conditioner 3 of the back side location. The air conditioning capacity is set as the second setting capacity (for example, 100% capacity). In addition, when the adjacent region R1, the rear region R2, and the side region R3 are selected as the guidance area, the control unit 5 performs the front side operation in addition to the operation of the air conditioner 3 at the rear side portion with the second setting capability. The air conditioning capacity of the air conditioner 3 at the location is increased from the first setting capacity (for example, 70% capacity) to the second setting capacity (for example, 100% capacity).

  In this way, even when the number of areas to be classified and the number of air conditioners 3 provided in the classroom 1 are different, in addition to switching between operation and shutdown of the air conditioner 3, the air conditioning capability during operation of the air conditioner 3 is improved. By switching, the environmental state between the plurality of areas can be made different, and appropriate guidance control can be performed. In addition, as described above, by reducing the number of air conditioners 3 provided in the classroom 1 rather than the number of areas to be classified, the number of air conditioners 3 installed can be reduced, thereby reducing costs and improving energy savings. it can.

  And not only in the air conditioner 3, but also in the lighting device 2 and other various facilities, by switching the capability, it is possible to perform guidance control that changes the environmental state among a plurality of regions.

  Further, for example, the abilities of the lighting device 2 and the air conditioner 3 can be adjusted in a plurality of stages (for example, two steps of a small capacity and a large capacity), and the lighting device 2 and the air conditioner 3 are controlled with respect to the guidance area as guidance control. It is possible to operate with a large capacity and operate the lighting device 2 and the air conditioner 3 with a small capacity for an area other than the guidance area.

(3) In the above embodiment, in the preliminary control, the illumination device 2 and the air conditioner 3 are operated only for the preliminary operation region, and the illumination device 2 and the air conditioner 3 are stopped for the other regions. However, for example, it is also possible to operate the lighting device 2 and the air conditioning device 3 by adjusting the capabilities of the lighting device 2 and the air conditioning device 3 to the minimum capability for the entire area in the classroom 1.

(4) In the above embodiment, the control target space is divided into different forms for the illumination device region and the air conditioning device region. However, the illumination device region and the air conditioning device region have the same form. The control object space can also be divided. In addition, when the control target space is divided into a plurality of areas, for example, it can be divided into a plurality of areas according to the distance from the place where the platform is installed. This can be changed as appropriate.

(5) In the above embodiment, the counting unit 6 counts the number of people in the classroom 1 from the image data of the camera 7, but for example, the entrance to the classroom 1 and the entrance to the classroom 1 and from the classroom 1 It is possible to provide a detection unit for detecting an exit person, and to count the number of people in the classroom 1 based on the detection information of the detection unit, and the configuration of the counting unit 6 can be changed as appropriate.

(6) In the above embodiment, the control unit 5 repeatedly selects the guidance area in real time or every time the set period elapses, and only when the guidance area is enlarged, according to the selection of the enlarged guidance area. The illumination device 2 and the air conditioner 3 can be switched between operation and operation stop.
That is, when the guidance area is enlarged, the environmental state is made different between the guidance area and the outside of the guidance area, and the person in the control target space 1 is guided to the enlarged guidance area. On the contrary, when the guidance area is reduced, the environment before the selection of the guidance area is maintained without controlling the facilities 2 and 3 according to the reduced guidance area. Thereby, it is not necessary to move to the guidance area where the person in control object space 1 contracted by decrease of the number of people in a class.

(7) In the above embodiment, when the attendance number can be grasped before the lesson starts, the control unit 5 selects a guidance area according to the grasped attendance number, and the guidance area and other areas are selected. It is also possible to guide the people in the classroom 1 to the guidance area before the start of the class by changing the environmental conditions. Thereby, the person who enters the classroom 1 before the lesson start can be guided to the guidance area. In addition, by selecting the guidance area according to the number of people in the classroom 1 counted by the counting unit 6 at the start of the lesson, the selection of the guidance area according to the number of people in the room at the start of the class and The guidance to the guidance area can be performed appropriately.
